Hi All,
I seem to be inexplicably running into TAP5-299
(https://issues.apache.org/jira/browse/TAP5-299), even though I'm not
doing that.
Code is below. If anything exists in the "selected" listed, I get an NPE.
Am I doing something wrong?
-----------------------------------------------------public class EditQuery {
@Inject private QueryService queryService;
@Inject private CategoryService categoryService;
@Inject private Messages messages;
@InjectPage private Queries queries;
@Persist private Query query;
@Property private final ValueEncoder<Category> encoder = new
CategoryValueEncoder(categoryService);
@Property private final SelectModel model = new
CategorySelectModel(categoryService.getCategories());
@Persist @Property private List<Category> selected;
void onActivate() {
selected = new ArrayList<Category>();
selected.addAll(query.getCategories());
}
Object onActionFromCategoriesForm(){
query.getCategories().clear();
query.getCategories().addAll(selected);
queryService.saveQuery(query);
return queries;
}
public Query getQuery() {
return query;
}
public void setQuery(Query query) {
this.query = query;
}
}
--------------------------------------
public class CategoryValueEncoder implements ValueEncoder<Category>{
private CategoryService categoryService;
public CategoryValueEncoder(CategoryService categoryService){
this.categoryService = categoryService;
}
public String toClient(Category arg0) {
return arg0.getCategoryName();
}
public Category toValue(String arg0) {
return categoryService.getCategory(arg0);
}
}
--------------------------------
public class CategorySelectModel implements SelectModel {
private List<OptionModel> categories;
public CategorySelectModel(List<Category> categories){
this.categories = new ArrayList<OptionModel>();
for (Category category : categories){
this.categories.add(new
OptionModelImpl(category.getCategoryName(),category));
}
}
public List<OptionGroupModel> getOptionGroups() {
return new ArrayList<OptionGroupModel>();
}
public List<OptionModel> getOptions() {
return categories;
}
public void visit(SelectModelVisitor arg0) {
for (OptionModel category : categories){
arg0.option(category);
}
}
}
